Unload startup map


I wanted some help with unloading the startup map (my main menu). I wasn’t able to determine the first time you run the map if it was an level instance or a stream. I currently have map transitions with Load Level Instance and unloading of the second level with Should be Loaded to false and this works. but I am not able to unload, and remove from the game, the assets in the main menu since I didn’t unload it.

Basically main menu (A)-> level 1 → main menu (B) /level2 (I can unload level 1 or main menu B but main menu A still exists since it was the start up and I don’t have a reference to it)

I’ve tried Unload Stream level and passed it the map name and I can’t cast it to a level streaming kismet to call should be loaded to false.

Any advice?
